A group of students were asked whether they take French class, Art class, both classes or neither classes. The table shows the probabilities of the resultsArt | Not Art | TotalFrench | 0.2 | 0.4 | 0.6Not French | 0.35| 0.05 | 0.4Total | 0.55 | 0.45 | 1.00Let A represent taking French class and B represent taking Art class.Which statement is true?A. Taking Art class and taking French class are not independent events because P(A|B)=P(A) and P(B|A)=P(B) .B. Taking Art class and taking French class are independent events because P(A|B)=P(A) and P(B|A)=P(B) .C. Taking Art class and taking French class are independent events because P(A|B)≠P(A) and P(B|A)≠P(B) .D. Taking Art class and taking French class are not independent events because P(A|B)≠P(A) and P(B|A)≠P(B) .<<<<<<<
